The skill of spatial learning and orientation is fundamental in humans and differs widely among individuals. Despite its importance, however, the malleability of this skill through practice has scarcely been studied empirically, in contrast to psychometric spatial ability. Thus, this article examines the possibility of improving the accuracy of configurational understanding of the environment by training. A total of 40 adults with a poor sense of direction participated in the experiment; and were randomly assigned to either a condition in which they received feedback only or a condition in which they additionally practiced allocentric spatial updating. Participants walked one route in each session, once a week for 6 weeks, and conducted spatial tasks designed to assess their knowledge of the route. A total of 20 people with an average sense of direction also participated as a comparison group. Results showed that training in allocentric spatial updating improved the accuracy of direction estimates, although the size of the effect was limited: the improvement was not large enough to equate the performance in the groups with a poor versus average sense of direction. The two groups, however, did not differ in spatial skill in mental rotation or path integration. Feedback was effective for improving accuracy in straight-line distance estimates and sketch maps: repeated trials with feedback led to improved accuracy by the sixth session to a level comparable to the group with an average sense of direction. The results show that flexible translation between viewer-centered and environment-centered representations is difficult and not readily trainable, and provide insights into the nature of individual differences in large-scale environmental cognition.
空间学习和定向技能在人类中至关重要,个体之间存在广泛差异。然而,尽管这种技能非常重要,但与心理空间能力相比,其实践可塑性在经验上几乎没有得到研究。因此,本文探讨了通过训练提高环境构形理解准确性的可能性。共有 40 名方向感差的成年人参加了实验;他们被随机分配到仅接受反馈的条件或另外进行非定向空间更新练习的条件。参与者每周一次在每个会话中走一条路线,共进行 6 周,同时进行空间任务,以评估他们对路线的了解。共有 20 名方向感平均的人也作为对照组参加。结果表明,非定向空间更新训练可以提高方向估计的准确性,尽管效果有限:这种改进不足以使方向感差的组和方向感平均的组的表现相等。然而,这两组在心理旋转或路径整合的空间技能方面没有差异。反馈对于提高直线距离估计和草图地图的准确性是有效的:经过六次试验后,有反馈的重复试验可将准确性提高到与方向感平均的组相当的水平。结果表明,在以观察者为中心和以环境为中心的表示之间进行灵活转换很困难,并且不容易训练,这为大规模环境认知中的个体差异的本质提供了一些见解。
